Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 40,605,877, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 40,605,877 | |
| -1 | -40,605,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,605,877.
Example:
1 x 40,605,877 = 40,605,877
and
-1 x -40,605,877 = 40,605,877
Notice both answers equal 40,605,877
With that explanation out of the way, let's continue. Next, we take the number 40,605,877 and divide it by 2:
40,605,877 ÷ 2 = 20,302,938.5
If the quotient is a whole number, then 2 and 20,302,938.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 40,605,877 | |
| -1 | -40,605,877 |
Now, we try dividing 40,605,877 by 3:
40,605,877 ÷ 3 = 13,535,292.3333
If the quotient is a whole number, then 3 and 13,535,292.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 40,605,877 | |
| -1 | -40,605,877 |
Let's try dividing by 4:
40,605,877 ÷ 4 = 10,151,469.25
If the quotient is a whole number, then 4 and 10,151,469.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 40,605,877 | |
| -1 | 40,605,877 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 221 | 403 | 527 | 5,927 | 6,851 | 77,051 | 100,759 | 183,737 | 1,309,867 | 2,388,581 | 3,123,529 | 40,605,877 |
| -1 | -13 | -17 | -31 | -221 | -403 | -527 | -5,927 | -6,851 | -77,051 | -100,759 | -183,737 | -1,309,867 | -2,388,581 | -3,123,529 | -40,605,877 |
